VENTILATOR Application filed March 29, 1928.

'This invention relates to improvements in ventilators.

Heretofore ventilators for use in storm sashes have not been provided with means for preventing the circulation of air between the storm sash and the inner window when the ventilators are being used. This circulation of air is very objectionable, as in severe Winter weather it causes a frost formation on the inside of the window, which in the course of time melts and drips upon the inner window sill. Thus, in order to use the old type of storm sash ventilator, it was necessary to sacrice the benefits ordinarily derived from a storm window.

It is one of the objects of this invention to overcome the above-mentioned objection and to provide a ventilator which, in either the open or closed position, will prevent the circulation of air between the storm sash and the inner window, and the resulting accumit lation of frost.

It is a further object of this invention to provide a ventilator for use in storm sashes which will be automatically regulated by the opening` and closing of the inner window.

It is a further object of this invention to provide a ventilator for storm sashes in which a strip afliXed to the inner window and movable therewith, is employed to open and close openings in the storm sash.

It is a further object of this invention to provide yielding means in connection with said strip to cause it to bear tightly against the storm sash to most effectively accomplish its purposes.

It is a further obj ect of this invention to provide a ventilator which is simple in construction and operation, inexpensive to manufacture, and well adapted for the purpose described.

With the above and other objects in view, the invention consists of the improved ventilator, and all its parts and combinations, as set forth in the claims, and all equivalents thereof.

In the accompanying drawing, in which the same reference characters designate the same parts in all of the views:

Fig. 1 is a front elevation of a window Serial No. 265,753.

showing the application of this invention, the upper sash being lowered to expose the ventilator openings;

Fig. 2 is a vertical sectional view through the window and storm sash, parts being broken away;

Fig. 3 is a view similar to that shown in Fig. 2, with the exception that the upper sash is lowered; and

F ig. l is a detail View of the regulating 60 strip detached.

Jreferring to the drawing, the numeral 6 designates a window frame in which .there is a storm sash 7 having Ventilating openings S, and an upper inner sash 9, and lower sash 05 i0. To the upper edge of the upper sash, a regulating strip 11 is affixed by screws l2 which are countersunk in the stri 3 and which extend through a bore 13 of slightly greater diameter than the screw to allow movement of the strip on the screws. The side of the strip adjacent the inner window is provided with a plurality of recesses la for coil springs 15, the latter causing the strip to yieldingly bear against the storm sash.

Stop members 16 may be provided to limit the downward movement of the sash so as to prevent it from being lowered far enough to permit air to circulate between the storm sash and the window. S0

Rubber weather strips 17 extend along the upper and lower sides of the regulating strip to prevent air from entering the space between the strip and the inner sash.

The use of the invention is as follows: l/Vhen the inner sash is closed, as shown in Fig. 2, the regulating strip is in a position adjacent the openings 8 in the storm sash. The coil springs 17 cause it to bear tightly against the sash, preventing any air from entering. W'hen it is desired to ventilate the room, the upper inner sash is lowered until the stop member 16 is engaged, as shown in Figs. l and 3. This also lowers the regulating strip 1l and the openings 8 are exposed. The regulating strip is still contacting with the lower edge of the upper portion of the storm sash, preventing the air from circulating between the storm sash and the inner window,

but permitting it to enter the room to effectively ventilate the latter.

Although the ventilator has been described as positioned on the upper portion of the sash, it is not desired to be limited to that particular position, as the device will operate on the lower portion as well.

F rom the foregoing description it may be seen that the improved ventilator is simple in construction, automatic in operation, inexpensive to manufacture, and well adapted for the purpose described.

Vhat I claim is:

l. In a window frame the combination with a storm sash having an opening therein adjacent an end of the window frame, and a movable inner sash, of a regulating member secured to the inner sash and movable therewith, said regulating member covering the opening when the inner sash is closedy and exposing the opening when the inner sash is opened.

2. In a window frame the combination with a storm sash having an opening` therein adjacent an end of the window frame, and a movable inner sash, of a regulating member secured to the outside of the inner sash and movable therewith along the storm sash to open and close the opening therein.

3. The combination with a storm sash having an opening therein, and a movable inner sash, of a regulating member secured to the inner sash and movable therewith, said regulating member covering the opening when the inner sash is closed andl exposing the opening when the inner sash is opened, and yielding means in connection with the regulating member, for causing the latter to bear tightly against the storm sash.

4f. In al window frame the combination with a storm sash having an opening in'one end thereof adjacent an end of the window frame, and a movable inner sash, of an elongated strip secured to the outside of the inner sash and extending its entire width, said elongated strip covering the opening when the inner sash is closed, andl exposing the opening when the inner sash is opened.

5. In a window frame the combination with a storm sash having an opening in one end portion adjacent an end'of the window frame, and a movable inner sash, of a strip securedv to the outside of theinner sash adjacent the opening in the storm sash, saidstrip covering the opening when the inner sash is closed, and exposing the openingfwhen the inner sash is opened.

6. The combinationwith a stormfsash'having an opening in one end portion, and a movable inner sash, of a regulating strip therefor having recesses therein, means for securing said strip to the inner sash, said strip being slightly movable on the securing means, spring members inthe recesses of. the strip, said strip covering the openingy in the storm sash when the inner sash is closed, and exposing the opening when the inner sash is opened.

7 The combination with a storm sash having an opening in one end portion, and a movable inner sash, of a regulating strip therefor having bores therein and having recesses, screws extending loosely through said bores and securing the regulating strip to the outside of the inner sash adjacent the opening in` the storm sash, said strip being slightly movable on the screws, spring membersl in the recesses to cause said strip to bear against the storm sash, said regulating strip covering theA opening in the storm sash when the inner sash is closed, and exposing the opening when the inner sash is opened.

8. The combination with a storm sash having an opening in one end portion, and a movable inner sash, of an elongated regulating strip therefor having bores and recesses therein, said strip having a length equal to the width of the window sashes, screws extending loosely through the bores in the strip and securing it to the outside of the inner sash adjacent the opening in the storm sash, said strip being slightly movable on the screws, spring members in the recesses to cause said strip lto bear against the storm sash, said regulating strip covering the open'- ing in the storm. sash when the innerl sashv is closed, and exposing the opening when the inner' sash is opened.

In testimony whereof Iaflix my signature.
